Link AC is made of a steel with a 65-ksi ultimate normal stress and has a 14  ×   1214⁢  ×   12 -in. uniform rectangular cross section. It is connected to a support at A and to member BCD at C by 3838 -in.-diameter pins, while member BCD is connected to its support at B by a 516516 -in.-diameter pin. All of the pins are made of a steel with a 25-ksi ultimate shearing stress and are in single shear. Knowing that a factor of safety of 2.85 is desired, determine the largest load P that can be applied at D. Note that link AC is not reinforced around the pin holes.
